I’ve had my 40W Laser Cutter for just over three months now and I feel that I’ve got a good grasp on how it operates. Overall this is a good machine but it leaves a lot to be desired and the quality control is certainly lacking. The manual (at least the one I received) is written in poorly translated English and it really just skips over many important functions of the laser cutter. In addition, the pictures in the manual were inaccurate and there were various ports/connections in the manual that just were not on my model. Being that I’m a mechanical engineer who is used to accurate documentation, this is just deplorable.

Try to search online about the” 40W Laser Cutter” , “Chinese laser cutter”, “eBay Laser Cutter” or “K40 Laser Cutter” for information. You might see some reviews or complaints but there is very little information about its operation or maintenance. Understandably, this is going to frustrate people who shelled out a few hundred dollars to purchase this machine so I figured I’d be the one to do a write up and potentially save you some headache from my experience.
